Installing a range hood in your kitchen can dramatically improve air quality and your cooking experience. Whether you're replacing an old unit or installing a brand-new one, understanding the proper steps is essential for a safe, efficient setup. This guide covers the detailed installation process for both ducted and ductless range hoods, as well as under-cabinet and wall-mounted models.

How to Install Range Hood
The installation steps for a range hood can vary depending on whether the unit is ducted (with a vent pipe) or ductless, and also whether it’s an under-cabinet (built-in) or wall-mounted model. Below is a detailed and professional explanation of the installation process for each type of range hood, highlighting both common steps and key differences in the procedure.
I. General Preparation (Applicable for All Types)
Tools Required:
- Drill with various bits
- Jigsaw or reciprocating saw
- Measuring tape
- Level
- Screwdriver and screwdriver bits
- Safety gloves
- Caulk gun (for weatherproofing)
- Pencil and masking tape (for marking)
- Wire cutters/strippers (for electrical connections)
Materials:
- Range hood (ducted or ductless)
- Mounting brackets and screws
- Flexible ducting (for ducted models)
- Vent cap/damper (for exterior venting)
- Electrical wire
- Electrical connectors
- Silicone sealant or weatherproofing caulk
Step 1: Turn Off Power & Disconnect Existing Hood (if applicable)
Turn off the power at the electrical panel to avoid electrical hazards.
If you are replacing an old range hood, carefully remove it with the help of a second person. Disconnect all power and venting connections.
Step 2: Position and Mark the Mounting Area
For under-cabinet models: Measure the required height for the range hood. Typically, it should be positioned 24 to 30 inches above the stove. Mark the mounting bracket locations on the underside of the cabinet.
For wall-mounted models: Ensure you have the right height above the cooktop (usually between 24 and 36 inches). Mark the position where the hood will be mounted.
Step 3: Install the Mounting Brackets
Under-cabinet models: Attach the mounting brackets to the underside of the cabinet, ensuring they are securely fastened. Use a level to verify the alignment.
Wall-mounted models: Attach the brackets to the wall, making sure they are properly aligned and secured to studs. Use a level to ensure the hood will sit straight.
Ducted Range Hood Installation (with Venting Pipe)
Step 4: Determine Venting Path & Cut Vent Holes
Interior Hole: Use the template provided with the hood to mark the location of the vent hole inside your kitchen. For a ducted range hood, the size of the hole depends on the diameter of the vent pipe (usually 6 inches). Use a jigsaw to cut the hole in the wall or the cabinet.
Exterior Hole: Move outside and mark the corresponding spot where the vent will exit the house. Use a drill or jigsaw to cut the hole through the exterior wall.
Step 5: Install the Vent Cap and Damper
Install a vent cap on the exterior of the house to allow airflow from the kitchen to the outside. Secure it with screws and seal the edges with silicone caulk to prevent air leaks.
Step 6: Connect the Vent Duct
Attach the vent duct (flexible or rigid metal pipe) to the exhaust port on the range hood. Extend the duct to the exterior vent opening and secure both ends with clamps.
Ensure the duct is as straight and short as possible for optimal airflow, with minimal bends to prevent blockage.
Step 7: Electrical Connections
Run electrical wiring from your power source to the range hood’s electrical box. Strip the wire ends and connect them using wire nuts or connectors. Match the wire colors (black to black, white to white, and copper to ground).
Double-check that the connections are secure before enclosing the wiring in the electrical box.

Step 8: Mount the Range Hood
With your helper, lift the range hood into position. Secure the range hood to the mounting brackets with screws. If it's an under-cabinet model, tighten the screws from inside the cabinet. For wall-mounted models, ensure the unit is level before securing it.
Step 9: Test the Range Hood
Once the unit is mounted, turn the power back on and test the fan, lighting, and venting. Ensure that the air is venting properly through the exterior vent and that the fan speeds work correctly.
Ductless Range Hood Installation (Recirculating)
For ductless range hoods, there’s no external venting pipe required. Instead, the air is filtered using charcoal filters and recirculated back into the kitchen. The installation steps are similar, but the key differences are:
Step 4: Install the Charcoal Filters
Ductless hoods typically come with a charcoal filter. Install the filter inside the hood by following the manufacturer’s instructions.
Step 5: Electrical Connections
Just like with ducted models, run the electrical wiring to the hood and connect the wires using wire connectors.
Step 6: Mount the Range Hood
Mount the hood in the same manner as for ducted models, but there is no need to install a vent cap or connect a duct. Secure the unit to the wall or under the cabinet as per your model’s instructions.
Step 7: Test the Range Hood
Turn the power back on and test the hood to ensure the fan is working. Since the air will be recirculated, check that the air filtration system is working properly.
Key Differences Between Ducted and Ductless Installation
-
Vent Hole: Ducted range hoods require cutting both an interior and exterior vent hole, while ductless models do not.
-
Venting Pipe: Ducted hoods need a vent pipe to expel air outside, whereas ductless hoods use filters to recirculate air.
-
Charcoal Filters: Only ductless models require installation of charcoal filters inside the range hood.
- Exterior Vent Cap: A vent cap and damper are necessary only for ducted models to allow airflow outside.
Can I Install a Ductless Range Hood?
Yes, ductless range hoods are easier to install because they don’t require external venting. They use charcoal filters to recirculate the air back into the kitchen. The installation process is similar but focuses on mounting the unit and installing the filter.
What Should I Do If My Range Hood is Not Turning on?
First, check the power supply and ensure the circuit breaker is not tripped. Next, verify that the wiring connections are secure. If the unit still doesn’t work, consult the troubleshooting section of your manual or contact the manufacturer for assistance.
How Much Does it Cost to Install a Range Hood?
Varies based on ducted vs. ductless, complexity, and professional help. Ducted systems generally cost more due to venting.
Ducted Range Hood: The total cost for installation can range from $300 to $1,000 or more, depending on the location and the extent of the work.
Ductless Range Hood: Costs can range from $150 to $500 for professional installation, with most of the expense going toward electrical work and mounting.
DIY Installation: If you install the range hood yourself, you will save on labor costs. For a DIY installation, you may only need to purchase materials like a vent kit (if ducted) and basic tools. This could bring the total cost down to $100 to $300, depending on the complexity of the installation.
Do Range Hoods Have to Be Vented Outside?
No, range hoods do not always have to be vented outside. Ductless Range Hoods do not need to be vented outside. Instead, they use filters (usually charcoal) to recirculate the air back into the kitchen, removing smoke, grease, and odors before doing so. Ductless systems are ideal for kitchens that don’t have an exterior wall or where external venting is not feasible.

Do You Need a Vent Hood For An Electric Stove?
Yes, even though electric stoves don’t produce the same level of heat as gas stoves, you should still have a vent hood above an electric stove. Even electric cooking can create smoke, grease, and strong odors. A range hood helps to clear these from your kitchen.
Conclusion
Installing a range hood can be straightforward if you follow the appropriate steps for your specific model. Whether you’re working with a ducted or ductless range hood, or installing an under-cabinet or wall-mounted version, careful preparation and proper execution will ensure a functional and efficient kitchen ventilation system.
